This report analyzes the significance of osteophytes in the overall pathologic scheme in patients with single-level or multilevel cervical spinal degeneration. ⋯ Spinal stabilization reduces the size of osteophytes. Facet distraction spacers are more effective in reduction of the size of DOL in both immediate and delayed postoperative periods.

Case Reports
Intraventricular tension pneumocephalus after subarachnoid haemorrhage and removal of an external ventricular drain.
Pneumocephalus is defined as an accumulation of air or gas in the intracranial space. It is a common complication after skull surgery or craniofacial trauma, sometimes also caused by gas-producing organisms in the context of an infection, and reported with cerebrospinal fluid draining procedures. ⋯ The acute management included therapy with normobaric oxygen. Despite the large volume of trapped air and its diffuse distribution inside the skull and spine, therapy with 100% normobaric oxygen appears to be safe and efficient for a rapid improvement of the patient's symptoms and the neuroradiological imaging.

Case Reports
Microsurgical Treatment of a Complex Cognard V Tentorial Dural Fistula with Superior Cerebellar Artery Supply.
This case video demonstrates a microsurgical technique for the clipping and obliteration of a Cognard V tentorial dural fistula (Video 1). The patient was a 49-year-old male who presented with progressive upper and lower extremity weakness over 12 months, with associated cervical spinal cord edema. The patient was initially misdiagnosed with transverse myelitis; however, abnormal flow voids on magnetic resonance imaging led to a cerebral angiogram being performed. ⋯ In addition, this case is unique in providing a surgical visualization of the meningeal superior cerebellar artery feeder contributing to this fistula, namely the artery of Wollschlaeger & Wollschlaeger. Postoperatively, the patient demonstrated significant improvement in upper and lower extremity strength, indicative of a successful recovery. The patient was discharged to rehabilitation, with continued motor improvement.

We aim to define the dynamic interplay between neurovascular-specific comorbidities and in-hospital complications on outcomes (functional outcome and mortality), length of stay (LOS), and cost of hospital stay. ⋯ Neurovascular comorbidities are the primary driver of poor mRS equivalent outcome, in-hospital mortality, higher LOS, and higher cost after ruptured intracranial aneurysm procedural treatment. The conditional event of complication influences patients with moderate comorbidities more so than those with low or high comorbidities.

Idiopathic normal pressure hydrocephalus (iNPH) negatively affects gait and cognition abilities and urine continence in the elderly. It is associated with systemic hypertension, although the exact pathophysiology is still unknown. A correlation to increased intracranial pulsatility and decreased compliance was suggested. Transcatheter aortic valve implantation (TAVI) is increasingly used in the treatment of severe AS. New-onset systemic hypertension affects some patients after TAVI. ⋯ This is the first case series of symptomatic NPH after TAVI. In this unique subgroup, NPH symptoms can develop rapidly. Post-TAVI iNPH represents a novel interaction between the blood and CSF circulations.
